The conclusion of the opening round of the main draw at the BB&T Atlanta Open 2018 saw five Americans advance into the round of 16, highlighted by local favorite Donald Young. Young recovered from a set down on Monday to win the second and third sets on Tuesday, saving a match point in the third, and also recovering from a break down in the third to prevail 2-6 7-6 7-6 against the veteran Croat. Karlovic’s normally steady serve failed him in the deciding set while Young was clutch to win just his second ATP match of the year.

Ryan Harrison also completed a comeback winning 4-6 7-6 6-1 over James Duckworth. With his wife cheering him on from the sidelines Harrison played a tough second set and a smooth third after struggling in the first, as Duckworth’s game melted in the heat. Taylor Fritz joins Harrison in the round of 16 after a routine 6-4 6-4 victory against Ramkumar Ramanathan. A tired Ramanathan generated no break point chances and struggled with his second serve.

Noah Rubin and Frances Tiafoe were the other Americans to win in straights. Rubin 6-3 6-4 over Thanasi Kokkinakis and Tiafoe 6-4 6-4 over Marius Copil. Neither Copil nor Kokkinakis generated a break in the match, as Rubin saved all three break points he faced.

In the other Tuesday singles matches, Cam Norrie ran away from a frustrated Malek Jaziri 7-5 6-0, Jeremy Chardy was too steady on serve against Ricardas Berankis winning 6-4 6-3. ATP veterans Marcos Baghdatis (6-4 6-1 against Alex Bolt), Mikhail Youzhny (6-2 6-0 against Emil Reinberg) and Mischa Zverev completed the R16 singles field. Zverev had match points in the second set tiebreak vs. Tim Smyczek but had to prevail in 3 sets 6-3 6-7 6-3 with his serve and volley game in a match that lasted over 2 and a half hours.

In doubles Donald Young and Chris Eubanks advanced in a third set tiebreak while Tiafoe/Bryan won in straights.

Tomorrow in singles it will be defending champion John Isner against Alex De Minaur, Hyeon Chung returning from injury against Fritz, Harrison against Lukas Lacko and veterans Youzhny and Zverev squaring off.
